Off to climb mountains in India soon.
I get using a charger for devices with USB ports, but what about removable batteries in cameras, such as my Canon Ixus?

I think it’s probably best just to get a job lot of spare batteries of t’ internet…

Can you not borrow a camera that takes normal batteries and then buy a load out there?

will the camera charge over usb or do you need to take it out and put it in a charger?

How long are you going for?
How many shots does a full (cold) battery give you?
How many hours a day can you get direct sunlight on a solar panel?

I’d think you would be spending quite a bit on a half-decent panel, then adding either a 12vDC camera battery charger (which they make for the Ixus) or another battery to charge, then use that to charge the camera battery. Either way, you need to work out how many shots per battery and do the sums on batteries v charging for cost and weight.
